I'm a shameless Gundam fan so this was kind of fun to make. It's another depth of field test using a Z-depth map, which I'd like to quickly explain how it works, if you're interested.
Basically, when you're setting up your Vray rendering paramaters, click on the "Render Elements" tab and click Vray_Zdepth. You type in a min and max number (the min being the closest thing you want in focus, the max being the furthest away object.) and it will render a z-depth map along with your beauty pass, and it looks like this:
You import this image into photoshop's channel tab and use it as an alpha map for your rendered image. This map tells photoshop what is close and what isn't, the lighter the image, the closer the object is to the camera. You can use this on the Lens Blur filter for simulating a realistic depth of field, among other things.
And this is what I did yesterday. I was making this to see how easily depth-of-field can create the sense of miniaturized models. A few friends commented saying they looked like a small scale-model of actual buildings, so I think I got the desired effect.
Anyways, hope you guys have an amazing weekend!
